DOWSIL™ Z-70 Emulsion

什么是 DOWSIL™ Z-70 Emulsion?

用作基于硅树脂底灰和涂层配方中的疏水添加剂，已知透湿度高、液体防水性好。也用于水泥基产品的外加剂，耐水性增强（例如铺路材料）。

For improving water resistance of silicone resin based renders
Admixture for cementitious based product with improved water resistance (e.g.pavers)

Can be diluted in water or used as supplied to provide hydrophobic properties in different applications
Induces water repellency to cured cement-based mortar
Silanol groups react chemically with hydroxy functional sites on the substrate, pigments or cement hydrates
Induces water repellency of dried silicone resins based render
Enhanced beading and hydrophobing effect can be achieved when used in conjunction with DOWSIL™ IE-2404 Emulsion in render
Addition levels of emulsion of hydroxyl functional polydimethylsiloxane fluid in render or cementitious material are ranged between 0.5 and 2 %
High water repellency and beading
High water vapor permeability
Increased resistance to UV degradation
DOWSIL™ Z70 Emulsion used as admixture in cement formulations provides excellent liquid water repellency to cured mortar
